JULIUS MANN, 0F NEW YORK, N. Y.

LOCK.

Application led July 29, 1921. Serial No. 488,439.

To @ZZ whom t may concern:

Be it known that 1, JULiUs MANN, a citizen of Poland (having taken out first United States citizenship papers), and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and 1mproved Lock, of which the following is a full, clear, and exact description.

This invention relates to locks and has for an object to provide an improved construction which may act in the ordinary capacity of door locks or may act in conjunction with a link as a safety catch for a door when aj ar.

Another object of the invention is. to provide a locking structure with a locking bolt and a link pivotally mounted on the keeper of the lock arranged to co-act with the bolt to present allinkl safety device for holding the door partially open and at the same time locked.

Another object of the invention is to provide a lock with a locking bolt and mechanism for actuating the same which in addition, acts to lock the bolt against actuation when set to certain positions.

An additional object of the invention is to provide a lock which may be set against operation by an authorized person or an unauthorized person from the outside or from the inside.

ln the accompanying drawings-.

Figure 1 is a vertical longitudinal sectional view through a lock embodying the invention as the same appears when in use, the section being taken on line 1 1 of Figure 2.

Figure 2 is a horizontal sectional view through Figure 1 on line 2-2.

Figure 3 is a view similar to Figure 'l but showing the partsv ina dierent position. l

Figure 4 is a fragmentary sectionalview similar to part of Figure 3 but showing the locking mechanism in a diderent positon.

Figure 5 is a view similar to Figure 4 but looking at the locking mechanism from the opposite direction.

Figure 6 is a view similar to Figure 5 but showing the parts in a different position with the bolt slightly advanced toward a projected position.

Figure 7 is a sectional view through Figure 1 approximately on line 7 -7.

Figure 8 is an inverted viewof a locking bar embodying certain features of the invention.

Referring to the accompanying drawings by numeral, 1 indicates a door of any desired kind and 2 a door jamb. with the door l is a lock 3 and connected with the jainb 2 is a keeper 4 of a special construction and provided with a link 5 which acts in a general way the same as a Lnight chain now in common use. The keeper 4 is enlarged at its outer end so as to present locking abutments 6 and 7, said abutinents being spaced apart in order to present a groove 8, These abutnients are also undercut to yprovide passage-ways 9 for the bolt 10. This bolt is provided with a spring receiving stem 11 and laterally extending shoulders 12, a neck l'and a locking head 14. rlhe locking head 14 is wider than neck 13 and is provided with rounded shoulders 15, which under some circumstances, strikes the rounded surfaces 16 of members 6 and 7 Each of these members is provided with a lug 17 which carries a pivot 18 and which isprovided with two flat surfaces 19 and 20. These surfaces are adapted to be engaged at different times by the spring 2l so as to resiliently hold the Connected link 5 in the position shown in Figure 2 or enlarged opening 23 through which the head 14 of bolt la() may project, said opening merging into a restricted'notch 24 which readily accommodates the neck 13 of bolt 10 but through which the head 14 cannot pass.

When the parts are in the position shown in Figure 2, the'bolt 10 may be projected outwardly andv the head 14l forced through opening 23. The link 5 may then be swung over manually to the dotted position shown in Figure 2 and after which the door 1 opens as indicated in dotted lines in Figure 1. It will be noted that when this takes place the door is locked-against opening beyond the length of the link 5 and that the door must be closed before the bolt can be retracted. Also, by reason of the undercut portions of members 6 and 7 for provid-ing the grooves 8, the bolt 10 must be projected in order to open the door and if projected will extend into the opening 23 but will not interlock With'the link 5 unless said link is manually moved over to the dotted position shown in Figure 2. In case the door should be open and the bolt 10 retracted, the door may be readily closed by using some force, as the curved surfaces 15 of the bolt head 14 will strike the curved surfaces 16 of members 6 and 7 and will be automatically projected against the action of the spring 25 and then retracted into the position'shown in Figure 1 which is the locking position.

It will be evident that the bolt 1() and associated parts forming the lock may be used in connection with. the keeper 4 either with or without the link 5 though this particular form of bolt is especially adapted for usel in connection with this link.

In constructing the lock, the bolt 10 is carried by a casing 26 which is provided 'with a division wall 0r partition 27 having an apertureI 28 formed therein as well as a notch 29, said `aperture accommodating the shank 11 While the notch 29 accommodates the shoulders 12. It will, therefore, be seen that the bolt 10 is guided by the shank 11 operating in the aperture 28 and the neck 13 operating in the aperture 30 formed in theend of casing 27,. They shank 11 of the bolt 10 is rigidly securedto an end member' or abutment 31, which end member or abutment is provided with a flange 32 and a shoulder 33 preferably'provided with a contact surface 34arrangedvat a slight angle to the remaining part of the shoulder in order to engage properly the end of the locking bar 35 hereinafter fully described. The abutment 31 reciprocates with the bolt 10 and when moved to the position shown in Figure 3 compresses spring 25. In order to move the abutment- 31 together y with the bolt 10 against the action of spring 25, two actuators are provided, namely, actuators 36 and 37, actuator 36 being connected with.

the hand operated knob 38 arranged interiorly of the door 1l while the actuator 37 is connected with the mechanism of an ordinary tumbler lock 39. The tumbler lock 39 is operated by a key in the usual manner and when rotated rotates the actuator 37 in either direction as desired for locking or unlocking the lock 3. However, these actu ators arevso formed as to be set not only to lock the ybolt 10 in a locking position but to lock the bolt against actuation by the opposite actuator.

When the parts-are in the position shown in Figure 1, either actuator may operate the bolt while the position of the parts in Figure 4 shown with the bolt may be actuated only by the actuator 36. When the parts are in the position shown in Figure 5, the bolt can be actuated only by the actuator 37.

-In this way thelock may be set to prevent anyone from the exterior unlocking the 36 is rotated in the direction of arrow 4() until the notch 41 straddles the flange or web 32 as illustrated in Figure 4. rll`he abut-y ment 31 is cut away on ythe lower surface except near the end carrying the web 32, which end is provided with an extension 42; 1n this way, ample space is assured for the free passage of the'actuator 36 beneath the abutment and around to the position shown in Figure 4. Preferably, bothends of the actuator 36 are bent vupwardly from the body of the actuator so that the part carrying the notch 41 will readily strike web 32 when moved to the position shown in Figure 4 and the actuating end 3,6' will strike the projection 42 when the actuator is operating to project the bolt as shown in Figure 3.

1t is, of course, understood that the actuator 36 is connected with the knob 38, said connection being in any desirable manner, as for instance, by a suitable short shaft 43, which is rigidly, secured to the actuator 36 extends through the wall of'casing 26 and is rigidly secured to the knob 38. When the parts are in the position shown in Figure 1 and it is desired to actuate or project the bolt 10, a key is inserted into the locking mechanism 39 and rotated in the direction indicated by the arrow 44 in Figure 3. Vhen this has been done, the bent up section l45 of the actuator 36 will engage the abutment 31 adjacent the shoulder 33 and will move the parts to their projected position l f y 1n Figure 6, the actuator 37 is shown as beginningto project the bolt. It willV be noted that the bar 35 is resting against pin 46 and is held in that position by a spring 47 actingy against theflatsurfaces 48.v When the l,bar 35 is resting against the pin 49, spring 47 acts against the surface 50 for preventing accidental shifting of the bar. The v knob 38 as shown in Figure 2 isv connected to the inner wall 51 ofthecasing' 316i-and when in the position shown in Figure 6 is out of the way of the shoulder 33 so'that the bolt may freely reciprocate. 1n .case it shouldbe desirable to lock the bolt against I operation from the insideor bythe knob 38, the actuator 37 is moved in the oppositedirection to the arrow 44 (Fig. 3) until the same shifts the bar 35 'to the position shown in Figure 5. "When in this position, the end of the bar 35 is in the path of movement of the vshoulder 33 and, consequently,` the. bolt 10 cannot be moved against the action of spring 25. lNhen the' parts are in this po-` sition, knob 38 cannot shift the boltfwhich can be done only byactuator 37y which is moved by the locking mechanism 39 and the actuator 37 can only actuate the bolt after it has first shifted the bar 35 back to the position shown in Figure 4. It will be noted that the bar 35 is pivotally mounted on the wall 5l and freely swings except for the action of spring 47. This bar is provided with an undercut 52 which permits the extension 53 of 'the actuator 37 to freely pass when moving from the position shown in'Figure l to that shown in Figure 6. In moving in this direction, the extension 53 acts to throw the bar 35 back to its inoperative position as shown in Figures 4 and 6.

What l claim is 1. A lock comprising a keeper, a bolt, means for actuating said bolt `trom the interior, means for actuating said bolt from the exterior, and a spring pressed locking bar pivoted adjacent the bolt actuated by the exterior operating means preventing operation of said bolt from the interior after it has been locked from the exterior.
